Types ¶
type ConfigFunc ¶
type ConfigFunc func(fbm *Fbm)
func WithFreq ¶
func WithFreq(freq float64) ConfigFunc
WithFreq sets frequency of fbm, should be a sufficiently low number.
func WithLacunarity ¶
func WithLacunarity(lacunarity float64) ConfigFunc
WithLacunarity sets lacunarity of fbm, must be value greater than 1. Lacunarity is strength of each cascading frequency per octave.
func WithOctaves ¶
func WithOctaves(octaves int) ConfigFunc
WithOctaves sets amount of octaves for fbm, this effectively means amount of times each noise will run on top of each other. Must be greater or equal 1.
func WithPersistence ¶
func WithPersistence(persistence float64) ConfigFunc
WithPersistence sets persistence of fbm, must be value in range (0, 1). Persistence is strength of each cascading amplitude per octave.
type Fbm ¶
type Fbm struct {
// contains filtered or unexported fields
}
func New ¶
func New(f ...ConfigFunc) *Fbm
New constructs a new *Fbm, setting parameters to reasonable default values: freq: 0.005, ampl: 1, octaves: 1, persistence: 0.5, lacunarity: 2.0. Accepts multiple ConfigFunc to customize instead of default values.
